The chemical recycling of end‐of‐life polymers can add some value to a future circular economy. In this regard, the hydrogenative degradation of end‐of‐life PLA was investigated to produce 1,2‐propanediol as product, which is a useful building block in polymer chemistry. In more detail, the commercially available Ru‐MACHO‐BH complex was applied as catalyst to degrade end‐of‐life PLA efficiently to 1,2‐propanediol under mild conditions. After investigations of the reaction conditions a set of end‐of‐life PLA goods were subjected to degradation.

钌催化氢化降解报废聚丙交酯生产 1,2-丙二醇作为平台化学品

报废聚合物的化学回收可以为未来的循环经济增加一些价值。在这方面，研究了报废 PLA 的氢化降解，以生产 1,2-丙二醇作为产品，这是聚合物化学中有用的构建单元。更详细地说，将市售的 Ru-MACHO-BH 复合物用作催化剂，在温和条件下将报废的 PLA 有效降解为 1,2-丙二醇。对反应条件进行研究后，对一组报废的 PLA 商品进行了降解。
